IDT74SSTUBH32865A
28-BIT 1:2 REGISTERED BUFFER FOR DDR2
COMMERCIAL TEMPERATURE GRADE
Operating Characteristics
The RESET and CSGateEN inputs of the device must be held at valid levels (not floating) to ensure proper device
operation. The differential inputs must not be floating unless RESET is LOW.
